DIPROV'EMET IN- WATER-:METERS The Schedule referred to in these Letters Patent and making pan. of the same.

To all whom it may concern Beit known that I, ISAAC CAREY, of- Warwick, in the county of Orange, and State of New York, have invented a new and useful Improvement in Tater- Meters; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enableothers skilled in theart to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a front sectional view of my invention, taken in the line :c z,'iig. 2.

Figure 2 is a section of the same, taken in the line y, fig; 1.

Similar letters of reference indicate'corresponding parts.

This invention relates to a new and improved watermeter, and is designed to measure and register the amount of Water used bythe occupants of a building.

The invention consists ofa tilting measure, L iran ged Ain connection with valves and water-supply and discharge tubes, as hereinafter fully shown and described, whereby the device is operated by the gravity of the water, as the latter passes through it, vand a correct measurement of the water which passes through the device obtained.

' In the accompanying sheet of drawings, A represents a case, of any suitable or desired dimensions, and B is a box, fitted in the case, and counterpoised or balanced on a tube', C, attached to the centre ofits under side, said tube being allowed to turn freely in the front and rear sides of the case, and having the supply or water-induction pipe attached to one end, a, and the discharge-pipe attached to the opposite end, b.

This counterpoised or balanced box B is divided into twoA compartments, D D', by a central partition, E, which is at right angles to the bottom of the box, as shown in iig. 1, and these compartments communicate respectively with the tube C by means of pipes c c', shown in bothtigures.

In the compartments DD there are placed and firmly secured small boxes, F F', and these boxes communicate, by means of pipes d d', with the tube C, the latter being provided with a partition or abutment, c, between the .pipes c c' and d df, as shown in iig. 2.

il'n the bottom of each box F F there is a valve, G, opening upward. 'Ordinary flap-valves will answer the purpose. These valves are connected respectively', by links H, to tilting-bars I I', which are secured to transverse rods j, the latter being at the centre of their under sides, and having their ends fitted in bearings y. In these bals there are secured tubes J J', which are partially filled with mercury, h. (See fig. l.)

K K' are valves, fitted respectively in the upperfpart of the compartments` D D'. These valves are each composed ofa plate, t', connected at one end, by a joint, j, to the under side of the top 0f the compartments, and having a fioat, k, at their outer or disengaged ends.

These valves, when closed, cover holes l in the tops of e the compartments.

cover the orifices of the pipes c c'.

The operation is as follows:

Suppose the box B to be tilted in the position as shown in iig. l, with the compartment D down, and Delevated. In this position of the box, the valve G of the small box F in I) will'be closed by the bar I, the gravity of the mercury hin tube J eiecting this, and, at the same time, keeping the orifice of pipe c open, so that the water in D will pass down, through c, into tube C, and thence into the discharge-pipe, attached to O at the end, 11, the closed valve G in F cutting oii" all communication between F and D.

In the elevated compartment D', the bar I covers the pipe c, and cuts oli all communication between the tube C and D', a result due to the mercury h in tube J', and, at the same time, the valve G, in the small box F, is kept open, so that the water Will flow up, through the pipe d', into box F', and thence into the compartment D', the latter gradually becoming lled, and increasing in weight, while, D is gradually discharging, and becoming lighter. This operation continues until D overbalanccs D, when the box B tilts, and D is depressed, and D elevated, the valve G in box F' closing, and the corresponding valve in bo'x F opening, the bars I I also tilting, under the changeof the position of the mercury h. in them, so that the orifice of the pipe c will be open, and the orifice of c closed. The water from D will then flow down c into C, and water fromtube C will flow up through d into F, and thence into the compartment D. The mercury-tubes J J canse' the bars or valves I I to act very eiciently, a result due tothe movement and gravity of the mercury.

By this simple arrangement, the water will be measured with greatexactness, any suitable indicating-apparatus being connected with the tilting box B.

The valves K K' are simply to admit air escaping from the compartments D D as they are filling, and admit-ting of the entrance of air as the water escapes from the same, the valves closing just prior to the iill` ing of the compartments, in order to prevent any escape of water through the holes l.

This meter 'may be constructed at a small cost, and will operate in a perfect manner.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patentl. The tilting box B, divided into two compartments, D D', with the boxes F F', fitted lwithin said compartments, and provided with valves G G, the boxes F F communicating with the tube C by the pipes d d', in connection with the tilting-bars or valves I I', arranged in relation with thc discharge-pipes c c', to operate in the manner substantially as and for the purpose set forth.

f2. The mercury-tubes J J', applied to the tiltingbars or valves I I', substantially as and for the purpose specified.
